That, too. For people who don't know what that is (source)

The motte-and-bailey fallacy (named after the motte-and-bailey castle) is a form of argument and an informal fallacy where an arguer conflates two positions that share similarities: one modest and easy to defend (the "motte") and one much more controversial and harder to defend (the "bailey").[1] The arguer advances the controversial position, but when challenged, insists that only the more modest position is being advanced.[2][3] Upon retreating to the motte, the arguer may claim that the bailey has not been refuted (because the critic refused to attack the motte)[1] or that the critic is unreasonable (by equating an attack on the bailey with an attack on the motte).[4]
